Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network resource allocation method, an apparatus, a terminal device, and a target base station.

Background

In the related art, a dedicated virtual network can be constructed for each service with specific requirements through a network slicing technique. A terminal device may be connected to one or more network slices through a 5G Access network under the control of an Access and Mobility Management Function (AMF) network element, when the terminal device requests registration, the Access network needs to select the AMF first and then select a slice through the AMF, and after the registration is completed, the AMF notifies the terminal device of slice information that the terminal device can connect to. When receiving the Session establishment request message of the terminal device, the AMF further initiates a Session Management Function (SMF) discovery and selection process in the network slice. Therefore, the mapping relation between the application and the network slice is configured on the terminal equipment side, so that the association between the application and the network slice is realized.

However, the above technical solution is not adapted to a scenario in which the terminal device moves at a high speed, and when the terminal device selects a network slice, an error may be generated between a network index obtained by its own measurement and a network index actually provided by the base station due to a moving speed, a base station coverage, and the like in an actual scenario, so that a network index actually used by the terminal device does not conform to a network capability provided by the network slice selected by the terminal device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a network resource allocation method provided in an embodiment of the present invention, which is applied to a terminal device, and as shown in fig. 1, the method includes the following steps:

step 101, acquiring first position information of the terminal device, and acquiring speed information of the terminal device.

In the embodiment of the present invention, the terminal device may be a terminal device in a high-speed moving scene, for example, a vehicle-mounted terminal device of a moving vehicle, or a mobile terminal placed in a moving vehicle.

In this step, current position information and speed information of the terminal device may be obtained first, where the current position information of the terminal device may be obtained by obtaining position information of the terminal device through a positioning module of the terminal device, such as a satellite positioning module and a differential base station positioning module, including coordinate positions in three directions of latitude x, longitude y and altitude z, to obtain an accurate positioning position P₀(x,y,z)。

When the terminal device cannot acquire the location information thereof through the self-contained location module (for example, the location module fails or the signal is not good and difficult to locate), the location information of the terminal device can be acquired in a base station ranging and locating manner, that is, the terminal device can transmit signals to a plurality of nearby base stations through an operator network, determine the distance between the base station and the terminal device according to the signal transmission response interval time manner, and then determine the location of the terminal device according to the plurality of distances. For example, as shown in fig. 2, the three base stations 20 near the terminal device 21 determine the straight-line distances d1, d2 and d3 between the terminal device 21 and each base station 20 by the arrival time of the downlink pilot signal or the difference between the times at which the downlink pilot signal is transmitted and received, respectively, and then may draw an arc, the overlapping position P of the three arcs, respectively, with the distance as a radius and the base station position as the center of the circle₀I.e. the position of the terminal device 21, the position P of the terminal device 20 can be finally determined by combining the map₀(x,y,z)。

The obtaining of the current speed information of the terminal device may be obtaining a moving speed vector of the terminal device through a speed measurement module of the terminal device

Wherein, as shown in FIG. 3, the velocity vector

Direction and target ofAnd the included angle of a connecting line between the base station S and the terminal equipment is theta. And under the condition that the terminal equipment does not have a speed measuring module, the positioning position P can be determined₀The value of the change Δ d with time t is derived to obtain a velocity value v, which is shown in FIG. 3 as the position P₀Is the direction of the velocity v.

And step 102, determining a base station list accessible to the terminal equipment according to the first position information and the speed information.

In the embodiment of the present invention, since the terminal device is in a high-speed moving scene, it is necessary to determine information of a base station to which the terminal device is to be accessed according to the position and moving speed information of the terminal device, and specifically, according to the information of the distance between the terminal device and a surrounding base station and the moving speed information of the terminal device, the information of the distance change between the terminal device and each base station in the next signal period is estimated, so as to obtain a list of base stations accessible to the terminal device in the next signal period, where the signal period may be a period in which the terminal device sends a measurement signal.

Optionally, the step 102 includes:

That is, in one embodiment, the time interval T of the terminal device sending the measurement signal and the velocity vector of the terminal device may be determined according to the time interval T of the terminal device sending the measurement signal

And the positioning position of the terminal equipmentPut P₀Determining the position information P of the terminal device at the next time of sending the measuring signal_nIn particular, it can be according to the formula

And (4) calculating. The time interval T for the terminal device to send the measurement signal needs to be greater than or equal to twice the single transmission time of the signal, and may be dynamically adjusted according to the speed of the terminal device, for example, the faster the speed, the shorter the time interval.

Then, according to the base stations around the terminal device, that is, the base stations within the preset range from the terminal device, and the position P of the terminal device when the terminal device transmits the measurement signal next time_nThe base station lists accessible to the terminal device are determined according to the sequence of the smaller distance and the larger distance, so that when a target base station, that is, a base station to which the terminal device is to be accessed, is determined, a plurality of base stations ranked in the top in the base station lists can be selected, for example, the top 3 base stations are selected as the target base station.

More specifically, the terminal device may be based on the current position P₀And (4) sequencing the distances from all the base stations around from small to large to establish a base station list L. If the single signal period time interval can be obtained, that is, the terminal device supports sending periodic measurement signals, the signal period time interval T and the speed of the terminal device can be obtained according to

Determines the position of the terminal device in the next signal period

Then, can be based on

The base station list L is updated by sequencing the distances between the positions of the base stations and the base stations around the base stations from small to large, and a database as shown in FIG. 4 is constructed.

Thus, by the embodiment, the accessible base station list of the terminal equipment in the next signal period can be accurately estimated.

And 103, determining a target network index actually required by the target application according to the preset network index of the target application on the terminal equipment and the speed information.

The target application may be an application that needs to configure a network slice on the terminal device, the preset network index of the target application may be a preset network index that is required by the target application, and the network index may include an uplink rate Vd-uplink (mbps), a downlink rate Vd-downlink (mbps), a time delay d (ms), a packet loss rate, and the like.

In the embodiment of the present invention, the influence of the speed information of the terminal device on the preset network index of the target application may be considered, and the target network index actually required by the target application at the current moving speed may be calculated, specifically, the influence factor of the speed on the network index may be determined through an experimental test, and then the target network index may be calculated by substituting the preset network index, the speed influence factor, the speed of the terminal device, and other parameters according to a specific formula.

It should be noted that the terminal device may send the speed information to an application management module of the communication module, that is, a Deep Packet Inspection (DPI) module, which classifies according to a security level built in each application to determine a network index required by each application, where the communication module may be a communication module integrated in the terminal device, or may be an individual hardware device, such as a Customer Premises Equipment (CPE).

In one embodiment, the target network indicator may be affected by a security level built in the target application and a speed of the terminal device, and a specific impact magnitude of the target network indicator and the speed may be determined by a preset security level impact factor and a preset speed impact factor, respectively, and finally a sum of impact values of the target network indicator and the speed impact factor is determined as the target network indicator.

That is, the calculation formula of the target network index may be: QoS ═ d_LS×LS+d_vX v, where QoS is a certain network indicator, LS is security level, v is the speed of the terminal device, d_LSAnd d_vSecurity level and speed impact factors, d, respectively, for corresponding network indicators in a single applied QoS_LSDetermined by QoS attributes, d_vDepending on the application class.

For example, the delay D attribute D in QoS_LSIntended to be set at 25ms, d for driving assistance applications_vThe time delay formula of the driving assistance application is set to be-1 ms · s/km and the safety level LS of the driving assistance application is set to be 4:

it should be noted that the values set in the above example are only used for explanation, the corresponding values in the actual scene still need to be calculated and verified by matching with a large amount of experimental data, the security level standard corresponding to each application still needs to be determined after being fully tested by combining the actual scene, and in this example, only a weighting algorithm of two independent influence factors is involved, while a plurality of complementary independent influence factors may be involved in the actual scene, and the calculation formula of the network index may be supplemented according to the influence degree.

Therefore, the implementation method can accurately and quickly calculate the target network index under the influence of the speed of the target application on the terminal equipment and the security level of the terminal equipment.

Step 104, sending the target network index to a target base station, so that the target base station distributes a network slice with network capacity matched with the target network index for the target application of the terminal equipment;

In this step, the target network index may be sent to a target base station, and certainly, a target application ID corresponding to the target network index may also be sent together, and after receiving the target network index, the target base station may allocate, according to the target network index, a network slice whose network capacity matches the target network index to the target application of the terminal device, that is, it is ensured that a network index possessed by the allocated network slice can be consistent with the target network index. The network capability represents the capability of the network slice to provide high and low network indexes, and the higher the network index the network slice can provide, the stronger the network capability of the network slice is, otherwise, the weaker the network index is.

The target base station may be a base station that is selected from the base station list according to a distance between each base station and the terminal device and is closer to the terminal device, for example, 3 base stations that are closest to the terminal device are selected, and then the target network indicator is sent to the three base stations respectively.

Optionally, after the step 102, the method further includes:

In other words, in an embodiment, considering that the terminal device will also generate a doppler shift in a high-speed moving scene, and the doppler shift may affect network indexes such as bandwidth and speed of communication between the terminal device and a base station, so that a network index actually experienced by the terminal device does not match a network index provided by the base station, the doppler shift generated by communication between the terminal device and a target base station may be calculated, so that the target base station may consider the effect of the doppler shift when determining a frequency of a signal transmitted to the terminal device.

Specifically, the doppler shift generated by the communication between the terminal device and the target base station may be calculated according to the speed information of the terminal device and the included angle between the moving direction of the terminal device and the target base station, for example, at least 3 base stations may be selected from the base station list L in the order of decreasing distance, and the doppler shift generated by the communication between the terminal device and each base station is calculated, assuming that the included angle between the moving direction of the terminal device and the connection line between the target base station S and the terminal device is θ, λ is a wavelength, and the speed of the terminal device is v, the doppler shift is calculated

After calculating the doppler frequency shift, the doppler frequency shift may be sent to the target base station, so that the target base station adjusts the frequency of sending a signal to the terminal device according to the doppler frequency shift, so as to counteract the influence of the doppler frequency shift on a network indicator; or, based on the doppler shift, determining a target frequency at which the target base station should send a signal to the terminal device, and then sending the target frequency to the target base station, so that the target base station sends a signal to the terminal device according to the target frequency, thereby avoiding a network indicator from being affected by the doppler shift.

In this way, by calculating the doppler shift generated by communication with the target base station and transmitting the doppler shift or the target frequency determined based on the doppler shift to the target base station, the error between the network index actually experienced by the terminal device and the network index of the network slice provided by the base station can be further reduced.

That is, in one embodiment, the target frequency may be equal to the initial frequency minus the Doppler shift, i.e., f_c＝f₀-f_dWherein f is₀Is the frequency required by the terminal equipment to the target base station under the condition of no frequency shift, namely the initial frequency f_dIs Doppler shift, f_cTo compensate for the doppler shifted target frequency.

That is, the doppler shift f can be set to meet the network index requirement corresponding to the target application_dOr target frequency f_cAnd the network slice selection module is used for recording the influence value of the Doppler frequency shift into a screening algorithm when the carrier frequency band is segmented and selected, and determining the network slice requirement corresponding to the target application. The Doppler may then be shifted by a frequency f_dOr target frequency f_cAnd sending the service request to a target base station, and enabling the corresponding network slicing service by the target base station. The detailed interaction flow among the important modules in the terminal device can be as shown in fig. 5, where an application management module of the terminal device initiates a speed acquisition request to a speed recording module and a selection request of a specific application to a network index to a network QoS operation module, and the speed recording module and the network QoS operation module return an authority authentication result to the application management module to determine whether the application management module has a request authority; the network QoS operation module waits for receiving the target application ID and the speed information of the terminal equipment; the application management module initiates a data transmission request to the speed recording module and determines a data transmission interval, the speed recording module returns speed information of the terminal equipment to the application management module in three times according to the transmission interval, and the application management module confirms that the speed data received in three times are within an error allowable range and successfully returns a speed mean value v to the speed recording module; the application management module sends a target application ID, a speed v and a target network index to the network QoS operation module; the network QoS operation module combines the Doppler frequency shift and the speed v to adjust the mapping relation between the target network index and the network slice, returns the network slice information mapped by the target network index to the application management module, and selects the sliceThe module sends a target application ID and target network slice information; the slice selection module completes the mapping relation between the target application ID and the network slices and returns a success message to the network QoS operation module.

Compared with the prior art, the invention has the following technical advantages:

1) through a communication system with speed, application and various data intercommunicating and interconnected among network slices, dynamic network resource allocation can be carried out from the application dimension according to different speeds of terminal equipment.

2) The association algorithm is optimized through the data acquisition mode of the speed, the position and the Doppler frequency shift value of the terminal equipment in the mode of assisting measurement by the communication base station, and the Doppler frequency shift error generated by terminal displacement between the network slice configuration received by the terminal equipment and the network slice configuration initiated by the base station is greatly reduced.

The network resource allocation method of the embodiment of the invention obtains the first position information of the terminal equipment and obtains the speed information of the terminal equipment; determining a base station list accessible to the terminal equipment according to the first position information and the speed information; determining a target network index actually required by the target application according to a preset network index of the target application on the terminal equipment and the speed information; sending the target network index to a target base station so that the target base station distributes a network slice with network capacity matched with the target network index for the target application of the terminal equipment; and the target base station is a base station of which the distance from the base station list to the terminal equipment meets a preset condition. Therefore, the target network index actually required by the target application is sent to the target base station by considering the influence of the speed information of the terminal device on the network index of the target application in the high-speed moving scene, so that the target base station can be ensured to distribute the network slice with the corresponding network capacity to the target application of the terminal device according to the target network index, and further the network index actually used by the target application of the terminal device is ensured to be consistent with the network capacity provided by the network slice.

Referring to fig. 6, fig. 6 is a flowchart of another network resource allocation method provided in the embodiment of the present invention, which is applied to a target base station, and as shown in fig. 6, the method includes the following steps:

step 601, receiving a target network index sent by a terminal device, where the target network index is a network index actually required by the target application determined by the terminal device according to a preset network index of the target application and speed information of the terminal device, and the target base station is a base station whose distance from the terminal device to an accessible base station list determined by the terminal device according to first position information and the speed information meets a preset condition.
